We had used vtkImplicitPolyDataDistance to calculate the distance from a point to the target points set in the post Calculate Distance From A Point To PolyData In VTK. We will try a new way using KD-Tree to find the closest point to the test point. The following example puts a Read more…

The post shows a way to move 3D model to the original point in world coordinate system. The file CMakeLists.txt is similar to https://www.weiy.city/2021/12/find-closest-plane-between-points-in-3d-by-covariance-matrix/. The included file point.hpp can be found in https://www.weiy.city/2020/09/project-point-on-line-and-plane-by-special-direction/. #include <iostream> #include <vtkPolyData.h> #include <vtkActor.h> #include <vtkTransformFilter.h> #include “./point.hpp” #include <vtkTransform.h> #include <vtkSTLReader.h> #include <vtkSTLWriter.h> #define Read more…

The post shows a way to calculate unsigned distance Between Two 3D Models. The models can’t have too low resolution because the result that vtkDistancePolyDataFilter computes will not be accurate. #include <vtkActor.h> #include <vtkCleanPolyData.h> #include <vtkDistancePolyDataFilter.h> #include <vtkNamedColors.h> #include <vtkNew.h> #include <vtkPointData.h> #include <vtkPolyDataMapper.h> #include <vtkPolyDataReader.h> #include <vtkProperty.h> #include <vtkRenderWindow.h> Read more…
